If I connect my SODAQOne V3 it's not visible in Windows. I tried it on 2 PCs and with different cables. When I power the SODAQOne it flashes blue and then glow green but nothing happened.Also no change in Bootloader mode. Green light changes from dark to light and back but device still not visible at all. Not even as unknown device.

HiThank you for the answer. Unfortunatly I've followed the steps bevor I wrote my post.

There is no com port visible at the devicemanager.I've also tested it on an other notebook and with a different cable.If I use an ArduinoUno everything works fine.Arduino IDE is Installed an the software know the SODAQOne as devicetype. But I have to chose a port if I want to connect it. The Portoption is grayed out. From online research I discovered the reason is for the grey field is that windows don't know the device. And I can confirm that nothing happened if I plug it in. Not even if I search for new hardware

Can you try putting the device in bootloader mode. This can be achieved by pressing the reset button twice in a row (only twice and about 0.5s apart). One of the LEDs (BLUE I believe) should stay on and slowly pulse.

In bootloader mode, the device should be visible on it's secondary COM port.

If this doesn't work, we might need to send you a replacement board. You should be able to open a ticket for a replacement via the webshop.

But unfortunatly after I tried it there is no change.The Port option is still grayed out.And there is no port visible in the device manager on windows.

As far as I understand it shouldn't be a driver problem. Usualy if there is no driver there will be at least an unknown device. But there is no change in the device manager if I connent the board with my notebook
